What Causes jet lag sleep disorder?
Jet-lag occurs when biological rhythms are disrupted as a result of rapid transitions across multiple time-zones. Such de synchronization of rhythms also occurs in nocturnal shift work employees who transfer to night shifts. The main but not the only cause of jet lag is crossing time zones. Usually going east is worse than going west. Children under three don’t seem to suffer jet lag badly as they are more adaptive and less set in their ways. Adults who adjust readily to changes of routine also seem less susceptible to jet lag. Those who are slaves to a fixed daily routine are often the worst sufferers. Jet lag is actually caused by disruption of your “body clock” – a small cluster of brain cells that controls the timing of biological functions (circadian rhythms), including when you eat and sleep. The body clock is designed for a regular rhythm of daylight and darkness, so that it is thrown out of “sync” when it experiences daylight and darkness at the “wrong” times in a new time zone
